Title: Wind power converter - has slot openings and aerodynamic surfaces, to generate or increase suction pressure
Inventor: BECKER FRIEDRICH
IPC: F03D1/04
Filed: 1991-01-05
Abstract: The device is for generation of a suction pressure by a moved air volume. An air flow is giuded over aerodynamic surfaces, and accelerated, which causes the static pressure to drop.

Title: Champagne bottle cork containing confetti - is divided partition into top and bottom parts with explosive powder, retaining and compression springs, and bolt
Inventor: CLASS WILHELM
IPC: B65D51/28
Filed: 1991-03-21
Abstract: The champagne-bottle cork (1) consists of a top, confetti-containing part (2) and bottom (3) part, divided by a partition (4). When the cork leaves the bottle-neck (7), the bottom part containing the ignition mechanism releases a retaining-spring (8) which flies up from a bolt's (12) retaining-notches. A compression-spring (19) forces the bolt through a foil seal (20) to ignite the powder which expands and throws the lid (21), confetti and cap (22) into the room. When the bottle is corked, the taut retaining-spring's outer part presses against the neck-wall and presses the part (9) of the retaining-spring running through the cork-centre into the bolt's holder-notches. The bolt-guide (26) is clamped by an annular serration (27) into the cork's lower part, and contains a stepped hole (34). ADVANTAGE - The explosive powder inside the cork pops the confetti out.

Abstract: New labelled nucleoside triphosphate derivs. (I) are ribonucleosides, 2'-deoxyribonucleosides or 2',4'-dideoxyribonucleosides, opt. in salt form, with a gp. of formula -(A)nQ linked to the nucleoside base, where: n = 0 or 1; A = an optional linking gp. stated to be an amino, alkyl, alkenyl, alkynyl, aryl, aralkyl or alkaryl gp. which may contain one or more terminal or internal structural functional units selected from amino, amido, imino, hydrazino, azo, triazene, keto, ester, hydroxy, ether, thioether, disulphide, ureido and thioureido gps., opt. substd. by alkyl, alkenyl, aryl, alkaryl or aralkyl gps.; Q = a gp. which is capable of complexing lanthanide ions and contains an 'energy donor' for lanthanide ions. Lanthanide complexes of (I) are also new. USE/ADVANTAGE - The complexes may be incorporated in oligonucleotides, e.g. by enzyme-catalysed tailing (using terminal deoxynucleotidyl transferase), to produce fluorescence-labelled hydridisation probes. They may also be used as markers in PCR amplification systems, as chain terminators (in the case of the dideoxy derivs.) in nucleic acid sequencing systems, and as tracers for measuring nucleic acid synthesis in vitro or in vivo. The lanthanide label can be detected by time-resolved fluorometry, which eliminates interference from autofluorescence and light scattering.
